Abstract
The utility model discloses a multilayer composite dust filtering bag, which is provided with two filtering layers; the filter layers sequentially comprise a bottom layer, a middle layer and an outer layer from inside to outside and are mutually laminated and formed, three edges of the two filter layers are respectively provided with a hot-pressing part, and the edges of the two filter layers are mutually laminated in a hot-pressing manner to form a bag shape; a cloth sleeve for connecting the two filter layers is arranged between the bottom layers of the two filter layers, the cloth sleeve is respectively attached between the two filter layers in a hot pressing manner along the length direction of the filter layers, and the opening of the cloth sleeve faces the bag opening; the cloth cover for connecting the two filter layers is arranged between the filter bags, so that the cloth bag is ensured not to bulge and deform after being filled with wind, and is easy to install and use; the utility model integrates a filter with initial effect and middle effect function in the filter bag, thus effectively saving cost and space; the non-woven fabric layer of the outer layer of the filter bag has the effects of smoothness, wear resistance and scratch resistance, and the service life of the filter bag is prolonged.
Description
Technical Field
The utility model belongs to the technical field of the filter layer and specifically relates to a compound dust bag that strains of multilayer is related to.
Background
The synthetic fiber filter bag and the non-woven fabric filter bag are made of super synthetic fibers by a special weaving method, so that the discomfort possibly caused by the old glass fiber material to a human body is avoided. The filter material contains electrostatic fibers, so that the filter material has particularly good filtering efficiency on the micron dust, and has the characteristics of high dust holding capacity, high air permeability, long service life and the like;
the prior filter bag has the following defects:
(1) when wind blows into the filter bag, the filter bag is enabled to be bulged, the filter bag can swing along with the change of the wind direction, and the stiffness is poor;
(2) primary filtration and medium filtration cannot be reused;
(3) the surface of the filter bag is not wear resistant.
For (2), the method in the prior art is usually a single primary filter bag or a single intermediate filter bag, and when the primary filter bag or the intermediate filter bag needs to be reused, the primary filter bag and the intermediate filter bag need to be sequentially arranged in the system, but the primary filter bag and the intermediate filter bag need to be disassembled, so that the disassembling step is added.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing the technical scheme that can solve above-mentioned problem.
The multilayer composite dust filtering bag is provided with two filtering layers which are square; the filter layers sequentially comprise a bottom layer, a middle layer and an outer layer from inside to outside and are mutually laminated and formed, three edges of the two filter layers are respectively provided with a hot-pressing part, and the edges of the two filter layers are mutually laminated in a hot-pressing manner to form a bag shape; a cloth sleeve used for connecting the two filter layers is arranged between the bottom layers of the two filter layers, the cloth sleeve is respectively attached between the two filter layers in a hot pressing mode along the length direction of the filter layers, and the opening of the cloth sleeve faces the bag opening.
As a further aspect of the present invention: the outer layer is a non-woven fabric layer with enough clearance and without influence on ventilation.
As a further aspect of the present invention: the middle layer is a middle-effect filter layer for filtering PM2.5 dust.
As a further aspect of the present invention: the bottom layer is a primary filter layer which can contain dust and can absorb larger particles.
As a further aspect of the present invention: the number of the cloth sleeves is at least three, and the cloth sleeves can be folded along with the extrusion between the filter layers and can be expanded along with the expansion between the filter layers.
Compared with the prior art, the beneficial effects of the utility model are that: the cloth cover for connecting the two filter layers is arranged between the filter bags, so that the cloth bag is ensured not to bulge and deform after being filled with wind, and is easy to install and use; the utility model integrates a filter with initial effect and middle effect function in the filter bag, thus effectively saving cost and space; and the non-woven fabric layer of the outer layer of the filter bag has the effects of smoothness, wear resistance and scratch resistance, so that the service life of the filter bag is prolonged.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
